The TMDL Program works with communities around the state to restore Texas waterways that have limited quality in relation to one or more of their assigned uses, such as recreation, fishing, or a healthy aquatic environment. The latest Index of All Impaired Waters, part of the Texas Integrated Report of Surface Water Quality, shows all impaired waterways and the strategies that are planned or underway to improve their quality.

In addition to developing and working with stakeholders to implement TMDLs, the program manages studies that determine the best management strategies for specific waterways. Learn more about TMDLs and How They Are Implemented.
